lake trout

or Mackinaw trout or Great Lakes trout or salmon trout

Large, voracious char (Salvelinus namaycush) found widely from northern Canada and Alaska to New England and the Great Lakes, usually in deep, cool lakes. They are greenish gray and covered with pale spots. In spring, 5-lb (2.3-kg) lake trout are caught in shallow water; in summer, fish of up to 100 lbs (45 kg) are trolled in deep water. Lake trout were virtually eliminated from the Great Lakes by the sea lamprey, which entered through the Welland Canal in the 1930s. They have been introduced in the western U.S., South America, Europe, and New Zealand.

There are two streams named Salmon Trout River in the Upper Peninsula of the U.S. state of Michigan.

Marquette County

Salmon Trout River in the Huron Mountains of Marquette County is home to the endangered "coaster" brook trout. The river flows into Lake Superior several miles northwest of Big Bay. The river rises in the northern portions of Michigamme Township and Marquette Township and flows through Powell Township. The headwaters of this river are in the Yellow Dog Plains.

The Huron Mountain Club (HMC), which owns a large tract of land in the mountains, including a portion of the Salmon Trout River. However, the private club zealously restricts access to its property, which is unfortunate for whitewater rafting enthusiasts since the Salmon Trout is rumored to be one of the best rafting rivers in Michigan.

This river has received attention lately as its head waters are located near a proposed sulfide mine. Groups opposed to this claim sulfide mining may lead to acid mine drainage that can adversely affect water systems, while proponents claim that sulfide mining can be done without adverse environmental effects.

Houghton County

Salmon Trout River in Houghton County flows into Lake Superior on the west side of the Keweenaw Peninsula near Redridge at 47°09'10" north latitude, 88°46'22" west longitude. The river rises in Adams Township, just north of M-26, between Painesdale and Toivola.
